Ansible ad-hoc
ad-hoc就是“临时命令”，执行完即结束，并不会保存
ad-hoc模式使用场景
比如在多台机器上查看某个进程是否启动，或拷贝指定文件到本地，等等
ad-hoc模式的命令使用

Ansible主机信息模块
这个模块非常实用
在公司中总会有一些需求
比如：
1.根据不同主机不同IP创建对应IP的目录
2.根据不同主机不同主机名创建对应主机名的目录
3.自动化运维平台需要自动获取到主机的IP地址，内存信息，磁盘信息，主机名...等
4.如果安装数据库，分配内存为物理内存的80%，此时有3台不同物理内存的机器2G、4G、16G
写一个playbook的情况下，我需要获取到对应主机的内存并作出计算，写判断。
setup
- 获取所有主机信息
